Hi there 4000$ is invested at 3% interest so the interest of this account is 4,000×0.03=120 be invested at 5% interest the total interest from the two investments is $195 120+0.05x=195 Solve for x to get the amount invested at 5% 120-120+0.05x=195-120 subtract each side by 120 0.05x=195−120 0.05x=75. Divide each side by 0.05 0.05/0.05 X=75/0.05 X=75/0.05 X=1,500 be invested at 5% Good luck!
